Chrysochromulina megacylindra

Original description: Cell conical, 5 µm long x 4 µm wide; flagella 2 equal, 20 µm long and a haptonema 18 µm long when extended. Scales of two types, inner, plate-like subcircular with a slightly thickened margin, diameter 1.0 µm, with a pattern of radiating ridges and an inconspicuous cruciform plane centre visible on both surfaces, but a thin band of concentrically striated material at the edge of the distal surface. Outer scales cylindrical, each cylinder straight-sided, very thin, diameter 0.5 µm, length 1.0 µm, attached to the outer surface of a base plate diameter 0.7 µm.
